The '''Marauder's Map''' is a [[magic]]al document that reveals all of [[Hogwarts School of Witchcraft and Wizardry]]. Not only does it show every classroom, every hallway, and every corner of the [[Hogwarts Castle|castle]], but it also shows every inch of the grounds, as well as all the secret passages that are hidden within its walls and the location of every person in the grounds, portrayed by a dot. It is also capable of accurately identifying each person, and is not fooled by [[animagus|animagi]], [[polyjuice potion]]s, or [[invisibility cloak]]s; even the Hogwarts ghosts are not exempted from this. The Map's only possible flaw lies in the fact that it cannot differentiate people who bear similar names (the shared names aren't given a Junior or Senior at the end). It can also reveal secret passages the Marauders found, though it only did this on one known occasion (in his [[third year]], [[Harry Potter]] was shown how to use the statue of the humpbacked witch to enter Hogsmeade Village).

One of the map's possible flaws lies in the fact that it cannot differentiate people who bear similar names (the shared names are not given a Junior or Senior at the end). Also, it does not seem to show unplottable rooms, since it was Dobby and not the map that showed where the Room of Requirement was or even existed. The Chamber of Secrets never appeared on the map; this could be because the creators never knew of it, or it could be unplottable as well, since when Ron and Hermione were in it collecting [[basilisk]] fangs, they did not appear on the map, like people did not appear when in the Room of Requirement.

+

+

The map can also reveal secret passages the Marauders found, though it only did this on one known occasion (in his [[third year]], [[Harry Potter]] was shown how to use the statue of the humpbacked witch to enter [[Hogsmeade|Hogsmeade Village]]).

The Marauder's Map was created by [[Remus Lupin]] (Moony), [[Peter Pettigrew]] (Wormtail), [[Sirius Black]] (Padfoot), and [[James Potter I|James Potter]] (Prongs) while they were attending Hogwarts. The map was created between [[1975]] and [[1978]], because the titles on the map refer to the nicknames of these men in their [[Animagus]] forms, and, in Lupin's case, [[werewolf]] form. The four created the map via the usage of the [[Homonculous Charm]], a powerful and advanced charm that enchanted the map to track the movements of everyone in the castle, as well as a [[charm to insult Severus Snape]]. This artefact proved quite useful to the foursome (commonly termed "the [[Marauders]]") through the years, until it was confiscated by [[Argus Filch]] in their final year at Hogwarts.<ref name="pottermorenew">''[[Pottermore]]'' - [http://www.pottermore.com/en/book3/chapter10/moment1/marauders-map New from J.

Harry used the Map throughout his time as a student at [[Hogwarts School of Witchcraft and Wizardry|Hogwarts]], especially during his [[1992–1993 school year|third year]], when he tried to find his way into [[Hogsmeade]]. Then, he used the [[One-Eyed Witch Passage]] which led into [[Honeydukes]] cellar. The map however will insult anyone who doesn't know how to activate it. Professor [[Remus Lupin]] did catch Harry with the map (after Snape found it while interrogating Harry), and subsequently confiscated it, surprising the younger wizard with his knowledge of how to activate it. It was through the map that the professor discovered [[Peter Pettigrew]] was still alive, leading him to conclude it was indeed the latter that had betrayed Harry's parents, in the process framing their old friend [[Sirius Black]] for the crime. This would go a long way towards repairing the rift between the two co-creators of the map. He would return the map to Harry before leaving Hogwarts, at the end of the year.

During Harry's [[1996-1997 school year|sixth year]], he used the map often when he spent a great deal of time obsessing over [[Draco Malfoy]]'s daily activities.

When monitoring [[Draco Malfoy]], Harry found he often disappeared off the map. The cause of this was not revealed until after he asked [[Dobby]] to trail Draco to find out what he was doing when he disappeared off the map. Dobby discovered that Draco was disappearing into the [[Room of Requirement]], which was not on the Marauder's Map. Whether because it was [[Unplottability|Unplottable]] or the Marauders never found the room is unspecified.

If someone tries to view the map without reciting the proper incantation, the map merely insults them and tells them to mind their own business. [[Severus Snape]] experienced this phenomenon when he tried to view the map by force.

An added bonus is that if the bearer of the map approaches the entrance to a secret passage protected by a [[password]], the password will appear on the map (usually as a speech bubble that appears close to the dot representing the Map's holder).

In some rare cases, the map may not be used to the best of its ability. Heading out through the secret passage from the [[Whomping Willow]] to the [[Shrieking Shack]] will make the person disappear, as [[Severus Snape|Snape]] mentions in the spring of [[1994]], so the Shrieking Shack is not included on the map because it goes off the edge of the map. It also does not show any person that may be inside the [[Room of Requirement]], as the Room of Requirement is unplottable and it itself does not show up on the map, or the Chamber of Secrets, as it is very unlikely that any of the creators of the map knew of its existence at the time that the map was made.

The Marauder's Map is a magical document that reveals all of Hogwarts School of Witchcraft and Wizardry. Not only does it show every classroom, every hallway, and every corner of the castle, but it also shows every inch of the grounds, as well as all the secret passages that are hidden within its walls and the location of every person in the grounds, portrayed by a dot. It is also capable of accurately identifying each person, and is not fooled by animagi, polyjuice potions, or invisibility cloaks; even the Hogwarts ghosts are not exempt from this.

One of the map's possible flaws lies in the fact that it cannot differentiate people who bear similar names (the shared names are not given a Junior or Senior at the end). Also, it does not seem to show unplottable rooms, since it was Dobby and not the map that showed where the Room of Requirement was or even existed. The Chamber of Secrets never appeared on the map; this could be because the creators never knew of it, or it could be unplottable as well, since when Ron and Hermione were in it collecting basilisk fangs, they did not appear on the map, like people did not appear when in the Room of Requirement.

The map can also reveal secret passages the Marauders found, though it only did this on one known occasion (in his third year, Harry Potter was shown how to use the statue of the humpbacked witch to enter Hogsmeade Village).

The Marauder's Map was created by Remus Lupin (Moony), Peter Pettigrew (Wormtail), Sirius Black (Padfoot), and James Potter (Prongs) while they were attending Hogwarts. The map was created between 1975 and 1978, because the titles on the map refer to the nicknames of these men in their Animagus forms, and, in Lupin's case, werewolf form. The four created the map via the usage of the Homonculous Charm, a powerful and advanced charm that enchanted the map to track the movements of everyone in the castle, as well as a charm to insult Severus Snape. This artefact proved quite useful to the foursome (commonly termed "the Marauders") through the years, until it was confiscated by Argus Filch in their final year at Hogwarts.[1]

Fred and George Weasley "nicked" the map from Filch's office in their first year at Hogwarts. They had been taken to his office for letting off a Dungbomb and saw a drawer marked "Confiscated and Highly Dangerous". George dropped another Dungbomb, while Fred stole the map from the drawer. They had to experiment with it in order to learn how to get it to work, but it gave them clues, "flickering into life here and there" when they came close to the activating phrase, until finally they got it exactly. Because of this map, the twins memorised the secret passageways of Hogwarts, which they used for quite a few of their many pranks.[2] In Harry Potter's third year at Hogwarts, Fred and George gave the map to Harry, so that he could go to Hogsmeade on the weekends, although he had not obtained a permission slip to do so from his guardians, Vernon and Petunia Dursley.

"Mr Moony presents his compliments to Professor Snape and begs him to keep his abnormally large nose out of other people's business.Mr Prongs agrees with Mr Moony and would like to add that Professor Snape is an ugly git.Mr Padfoot would like to register his astonishment that an idiot like that ever became a Professor.Mr Wormtail bids Professor Snape good day, and advises him to wash his hair, the slime-ball."

Harry used the map throughout his time as a student at Hogwarts, especially during his third year, when he tried to find his way into Hogsmeade. Then, he used the One-Eyed Witch Passage which led into Honeydukes cellar. The map, however, will insult anyone who does not know how to activate it. Professor Remus Lupin caught Harry with the map (after Snape found it while interrogating Harry), and subsequently confiscated it, surprising the younger wizard with his knowledge of how to activate it. It was through the map that the professor discovered Peter Pettigrew was still alive, leading him to conclude it was indeed the latter that had betrayed Harry's parents, in the process framing their old friend Sirius Black for the crime. This would go a long way towards repairing the rift between the two co-creators of the map. He would return the map to Harry before leaving Hogwarts at the end of the year.

During his fourth year, Harry used the map to help him as he sneaked into the prefects' bathroom to work on his clue for the Second Task of the Triwizard Tournament. On his way back, he dropped the map, and it was almost taken by Severus Snape. Harry was saved by Barty Crouch Jr, disguised as ProfessorAlastor "Mad-Eye" Moody, who pretended it was his. Due to the map's flaw, it could not differentiate between the Junior and Senior Crouches. Crouch later asked to borrow the map from Harry, but after Crouch was unmasked, he reclaimed it.

During Harry's sixth year, he used the map often when he spent a great deal of time obsessing over Draco Malfoy's daily activities.

When monitoring Draco Malfoy, Harry found he often disappeared off the map. The cause of this was not revealed until after he asked Dobby to trail Draco to find out what he was doing when he disappeared off the map. Dobby discovered that Draco was disappearing into the Room of Requirement, which was not on the Marauder's Map. Whether because it was Unplottable or the Marauders never found the room is unspecified.

While on the run in looking for Horcruxes, Harry would often look at the map to see what Ginny Weasley, his love interest, was doing, which would hint that the map works from any location.

The map is normally disguised as a blank piece of parchment. To view the map, one must tap it with one's wand and recite, "I solemnly swear that I am up to no good." The content of the map will reveal itself.

To hide the contents of the map so the parchment appears blank again, one must again tap it and recite, "Mischief managed."

An added bonus is that if the bearer of the map approaches the entrance to a secret passage protected by a password, the password will appear on the map (usually as a speech bubble that appears close to the dot representing the Map's holder).

In some rare cases, the map may not be used to the best of its ability. Heading out through the secret passage from the Whomping Willow to the Shrieking Shack will make the person disappear, as Snape mentions in the spring of 1994, so the Shrieking Shack is not included on the map because it goes off the edge of the map. It also does not show any person that may be inside the Room of Requirement, as the Room of Requirement is unplottable and it itself does not show up on the map, or the Chamber of Secrets, as it is very unlikely that any of the creators of the map knew of its existence at the time that the map was made.

Additionally, the map does not differentiate between two people with the same name. This was the case with Barty Crouch Jr, who was simply shown as "Bartemius Crouch" on the map (instead of "Bartemius Crouch Jr"). This lead Harry Potter to believe that Barty Crouch Sr. was in Hogwarts, when he was actually at his own home at the time.

Similarly, it identifies animagi by their actual name even when they are in their transformed state. It was by this mechanism that Lupin was able to identify Peter Pettigrew's presence at Hogwarts despite being presumed dead.

The map was impossible to be directly used by Severus Snape, as it was enchanted to insult him should he attempt to do so.[5] However, Snape was able to make use of the map to view Remus Lupin entering the secret passage underneath the Whomping Willow, as Lupin had left the map accessible beforehand.

The map also shows how to access the sealed passages by showing the password required to unseal it (displayed as a minuscule speech balloon shown close to the dot representing the user of the map that appears when the map's holder comes close to the available passages). More importantly, the map shows the name and location of every person within the Hogwarts grounds, even if they are wearing an Invisibility cloak (as demonstrated when Remus Lupin saw Harry Potter, Ron Weasley, and Hermione Granger sneaking to Rubeus Hagrid's cabin under Harry's Invisibility cloak), transformed animagi (evidenced by Lupin seeing Peter Pettigrew return to the school grounds from Hagrid's, despite being disguised as the rat Scabbers at the time), or under the influence of the Polyjuice Potion (as demonstrated when Harry saw Barty Crouch Jr, at the time disguised as Alastor Moody, ransacking Snape's office for more Polyjuice ingredients).

According to J. K. Rowling, Harry never gave the map to Teddy Lupin or any of his children, but his son James probably stole it from Harry's desk.

The magical defences on Hogwarts have been mentioned several times, including Hogwarts being unplottable. That implies that mapping Hogwarts is impossible, which is exactly what the Marauder's Map does. There are some possible loopholes for this: for example, making a place unplottable might simply make it impossible for it to be mapped with reference to somewhere else. As the Marauder's Map only covers Hogwarts, not its position relative to (for example) London, it would circumvent the theoretical unplottable charm.

The claim that the map shows "every" corner of Hogwarts is likely an exaggeration, as there is no indication that it shows the Chamber of Secrets or the Room of Requirement. However, the map was created based on the Marauders' knowledge of Hogwarts and as none of them were Parselmouths, they would not have been able to access the Chamber of Secrets. Considering that Fred and George had it during the opening of the Chamber of Secrets, and the disappearance of their sister into it, it seems very unlikely it showed the Chamber or they would have mentioned it. Also, it is possible that they did manage to find the Room of Requirement, but that the room itself is unplottable as need be[6]. However, it is not very likely the Marauders did discover the Room of Requirement as Sirius never suggested the Room to Harry as a possible location for the meetings of Dumbledore's Army in Order of the Phoenix. It is also possible that Sirius did not think about the Room of Requirement at the time.

In the book, the map is described as a single piece of parchment that could be laid on a desk in a classroom. In the film, the map is shown as a rather large, much-folded paper with several unfolding flaps within it.

In the film adaption of Harry Potter and the Prisoner of Azkaban, When Harry was walking down one of the corridors one night, he saw Peter Pettigrew's name appear on the map before being caught by Snape, which was the first hint of Peter still being alive. This did not occur in the book.

Harry retrieved the Marauders Map when Barty Crouch Jr took it, by simply taking it from the fake Moody's office at the end of the school year. (Rowling had forgotten to mention it.)[7]

Also in the film adaptation of Harry Potter and the Prisoner of Azkaban, while Albus Dumbledore is pacing in his office, his name is spelled Albvs Dvmbledore. This was most likely done simply to give the impression of age. During the late middle ages, 'v' and 'u' were used interchangeably, with 'v' always appearing at the beginning of a word and 'u' always appearing in the middle or at the end of a word.

The glossary on the Scholastic official website incorrectly claims that both Harry and Ron used the Marauder's Map to get to Hogsmeade.

The order of the nicknames on the map "Moony, Wormtail, Padfoot and Prongs" is actually in the reverse order of when the marauders died. Prongs being the first to die (October 31 1981), and Moony being the last (May 2 1998).This is Based on a Personal Observation.

A plot hole is that Fred and George Weasley never noticed Peter Pettigrew on the map in the 3 years they had it.
